7 '0 all whom it may concern Be it' known that I, EDWARD H. ANGIER, acitizenof the United States, and a resident of Framingham, in the countyof Middlesex and Commonwealth of Massachusetts, have invented anImprovement in the Art of Packaging Articles, of which the followingdescription, in connection with the accompanying drawings, is a,specification, like characters on the drawings representing like parts.

This invention relates to the art of packaging annular and otherarticles, and among other objects aims to provide a wrapper which maybequickly and effectively applied to such articles to form a neat andsecure package.

The character of the invention may be best understood by reference tothefollowing description of a wrapper and 'method of applying the sameillustrated in the accom panying drawings, wherein,

Figs. 1 to 4 are sectional views illustrating steps in the applicationof the wrapper'to an article; i

Fig. 5 is a partially broken away perspective view of a complete wrappedpackage;

Fig. 6 is a vertical section through the package shown in Fig. 5;

Fig. 7 is a vertical section through a pack age Wrapped in a mannersomewhat different from the package shown in Fig. 5;

Fig. 8 is a view of a portion of the wrapper showing the constructionpermitting the expansion of' portions thereof;

Fig. 9 is a perspective view of a portion of reinforced, waterproofpaper which may be desirably used as a wrapper; and

Fig. 10 is a partially broken away perspective similar to Fig. 5 showinga'package containing but a single tire.

The wrapper is particularly useful in forming a package containingarubber tire or a group of tires, and therefore for purposes ofillustration, the invention will first be described in connection with agroup of four tires, although obviously its field of use is notrestricted thereto. In Figs. 1 to 4 I have shown steps of wrapping thetires with the aid of suitable appliances which mi ht form parts of anorganized machine. y invention may be most readily understood from a"description of the steps and I therefore for convenience choose thatmethod of disclosing it.

Referring first, therefore, to Figs. 1 to 4:,

.the group of tires.

base mold 11, similar in form to mold 9, may a 1 designates a group offour rubber tires to be wrapped. To accomplish this a sheet of I Thepaper tube is placed on the mandrel so that its lower end portion 3 isthus flattened and spread out upon the table 7 --as shown in Fi 1. Thenthe group of tires is placed over the mandrel and paper tube and seatedon the lower end portion of said paper.

The group of tires may next be compressed in order that the wrapper mayfit closely thereto as more fully hereinafter de scribed. To accomplishthis a mold 9 is brought down against the top of the group of tires asshown in Fig. 2, with pressure sufiicient to properly compress them. Themold is preferably of skeletonized cupshape, having radial fingers whichare adjustable to vary the effective size of the mold. I

In the course of this last .step the lower endportion 3 of the paper maybe wrapped up about the lower, outer surface portion of To accomplishthis a be provided beneath the table 7, so that when the top mold 9 isthrust downward the supporting table 7 .and the group of tires thereonwill be pressed down into said base mold and the sides or fingers of thelatter will fold the lower end portion of the paper up into smoothfitting engagement with the lower, outer surface portion of the group oftires as shown in Fig. 2, the crimping-s of the paper opening andclosing as necessary to conform the wrapper to the shape of the tires.

Then the upper end portion 3 of the paper which projects loosely beyondthe mold 9 is folded outwardly down about the upper end portion of thegroup of tires. To accomplish this a presser 13 may be brought. down.

on the top of the group of tires to the posi tion shown in Fig. 3; Whilethe presser 13 holds the group of tirescompressed, the top mold 9 may bewithdrawn. The parts will then appear as in Fig. 3 with the end of thewrapper sheet 3 projecting outwardly beyond the edges of the presser.

The top mold 9 may then be lowered once again and will engage theprojecting end 3 of the'wrapper and fold it downwardly as shown in Fig.4 fitting it smoothly over the outer circumference of the annular groupof tires.

The paper may be of sufficient length so that the upper and lower endportions of the paper may overlap and be secured together, or they mayterminate with a space between them which may be bridgedby a connectingstrip. Preferably I secure the ends together as shown in Fig. 4 by astrip 15 which may have a gummed coating applied to the inner surfacethereof which when moistened will adhere to the end por-- tions of thesheet and securely hold' the wrapper about the article.

The tires should remain under compression a short time to allow thegummed coating to dry and then the cup-shaped topmold and the presserare lifted from the package and the latter may be then lifted from themandrel or the mandrel may be lowered' therefrom.

When the pressure is released from the package the tires will expandmore or less and maintain the wrapper in tight, closefitting engagementtherewith, thereby presenting a package of neat, finished appearance.

To facilitate opening of the package a strand 17 (Figs. 4 and 5) ofwire, cord or other suitable material may be applied to and adhere tothe inner surface of the connecting strip 15, so that when the latter isapplied to the package said wire will extend circumferentially thereofbetween the ends of the paper. An end 19 (Fig. 5) of the. wire mayproject out from the strip where 1t is conveniently accessible to begrasped and pulled. This will slit thestrip circ-umferentially thereof,and thereby separate the upper and lower portions of the wrapper whichmay be readily removed from the group of tires.

In Fig. 7 is shown-a package similar to the one described with theexception that the wrapper comprises separate end portions 21 and 23which are connected by an outer strip 25 and an inner strip 27. Anopener strand 29 is shown applied to the outer strip, but obviously sucha strand might be applied to the inner strip if desired.

In Fig. 9 is shown a desirable material for the wrapper comprising outersheets 31 and 33 having a layer 35 of black asphaltum or other suitablewaterproof adhesive between them. A series of reinforcing threads 37 areprovided, which may conveniently be introduced into the adhesive layer.Use of waterproof, reinforced paper is highly desir able because iteffectively protects the article wrapped from moisture and weather, andthe reinforcing threads enable the paper to withstand without rupturethe strain brought on the paper when the compression on the article isreleased and also assist the paper to withstand the wear and strainwhich it necessarily undergoes during handling or shipment of thearticle.

In Fig. 10 I have shown a package containing but a single tire insteadof four which is made in the same manner as the package shown in Fig. 5.i The tire is compressi le and is compressed in the wrapping operationand expands within the wrapper sheet 3 to form a closely Wrappedpackage.

Having described one illustrative embodiment of my invention withoutlimiting the same thereto, what I claim as new and desire to secure byLetters Patent is: p

1. A sealed package comprising an elastic tire having circumferentiallyextending wrapping material snugly enclosing it, said package beingharacterized by the fact that the tire is held under compression duringthe fitting and sealing of the wrapping material.

2. A sealed package comprising a plurality of elastic tires in lateralrelationship having circumferentia-lly extending wrapping materialsnugly enclosing them, said package being characterized by the fact thatthe tires are held under compression during the fitting and sealing ofthe wrapping ma terial.

In testimony whereof, I have signed my name to this specification.

EDWARD H. ANGIER.
